NCP1207A  
PWM Current−Mode  
Controller for Free Running  
Quasi−Resonant Operation  
The NCP1207A combines a true current mode modulator and a  
demagnetization detector to ensure full borderline/critical Conduction  
Mode in any load/line conditions and minimum drain voltage switching  
(Quasi−Resonant operation). Due to its inherent skip cycle capability,  
the controller enters burst mode as soon as the power demand falls  
below a predetermined level. As this happens at low peak current, no  
audible noise can be heard. An internal 8.0 ms timer prevents the  
free−run frequency to exceed 100 kHz (therefore below the 150 kHz  
CISPR−22 EMI starting limit), while the skip adjustment capability lets  
the user select the frequency at which the burst foldback takes place.  
The Dynamic Self−Supply (DSS) drastically simplifies the  
transformer design in avoiding the use of an auxiliary winding to  
supply the NCP1207A. This feature is particularly useful in  
applications where the output voltage varies during operation (e.g.  
battery chargers). Due to its high−voltage technology, the IC is  
directly connected to the high−voltage DC rail. As a result, the

The transformer core reset detection is done through an auxiliary  
winding which, brought via a dedicated pin, also enables fast  
Overvoltage Protection (OVP). Once an OVP has been detected, the  
IC permanently latches off.  
Finally, the continuous feedback signal monitoring implemented  
with an overcurrent fault protection circuitry (OCP) makes the final  
design rugged and reliable.
